Is it possible to do something like what is shown below using an Alert with a UITableView? If so, how can it be done?
read my this post - http://www.makebetterthings.com/blogs/iphone/add-uitextfield-in-uialertview/
and try to add a table or scroll view instead of uitextfield
No, that's not a UITableView. If you want to show something like that, use UIAlertView:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:#"Annuler" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil]; [alert show]; [alert release];

I have requirement, can I have Alert When,
1)Say 'B' View is Bigger View than 'A'.
2)'A' view is on top of 'B' view.
3)When 'A' view Crosses the Border of 'B' View using PanGesture then We Should get Alert.
if (!CGRectContainsRect(B.frame, A.frame))
{
NSLog(#"ALERT !!!");
}
In the target method of your pan gesture check if A view's frame is contained inside B view's frame by using CGRectContainsRect() method.
If it returens NO then show your alert.
if(!CGRectContainsRect(B.frame, A.frame)){
//show alert here
}
Try this one...
if (!CGRectContainsRect(B.frame, A.frame))
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:#"You have crossed." delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alert show];
}
if (!CGRectContainsRect(B.frame, A.frame))
{
UIAlertView * alert=[[UIAlertView alloc]initWithTitle:#"..." message:#".." delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil, nil];
[alert show];
}
try this one..
I need help on dismissing a UIAlertView programmatically. Currently I have this
UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:#"title" message:#"message" delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];
then later on I call this
[alert1 dismissWithClickedButtonIndex:0 animated:NO];
but nothing happens.
You need to set two things.
1. include your .h file : <UIAlertViewDelegate>
2. please follow below implementation...
UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:#"title" message:#"message" delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];
[alert1 show];
[self performSelector:#selector(dismiss:) withObject:alert1 afterDelay:1.0];
the dismiss method will be...
-(void)dismiss:(UIAlertView*)alert
{
[alert dismissWithClickedButtonIndex:0 animated:YES];
}
I hope this will help you.
I encountered this problem too.
In my case, for some reason calling:
[alert dismissWithClickedButtonIndex:0 animated:NO];
didn't work always (yes, even calling it on UI thread and yes, alert != nil), instead simply setting the animated flag to YES it worked:
[alert dismissWithClickedButtonIndex:0 animated:YES];
Maybe it's an Apple bug...
you should display it first:
UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:#"title" message:#"message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil];
[alert1 show];
then in delegate method
- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex{
if(buttonIndex==0){
// do something
}
}
The methods you called is correct.
I guess the alert1 is nil when your call the method dismissWithClickedButtonIndex:animated:
Try to check your variable alert1.
You can use the delegate method -alertView:didDismissWithButtonIndex: instead—it gets called once the alert view’s been removed from the screen, OR better approach is , use a background thread, e.g. with -performSelectorInBackground:withObject:, to handle whatever processing you need to do.
in my Alert View, there is two button, OK and Cancel. When the user click the OK button, the delegate method dismissWithClickedButtonIndex:animated get called, and if the index is 0, then i get called to a method to execute some code:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Alert"
message:#"Are you sure you want to exit"
delegate:self cancelButtonTitle: #"OK"
otherButtonTitles: #"Cancel",nil];
[alert show];
[alert release];//release the reference
Delegate method:
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{
if (buttonIndex==0) {
[self aMethod];
}
}
-(void)aMethod{
//Some useful code
}
Now, what i want to instead of all this, is to execute the code of the aMethod method in the AlertView directly, without referring to A delegate method and a method which get called, something like that:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Alert"
message:#"Are you sure you want to exit"
delegate:self cancelButtonTitle: #"OK" //Put here some useful code
otherButtonTitles: #"Cancel",nil];
Is it possible?
Unfortunately this is not possible at this time (iOS 5.1). The AlertView class does not support blocks.
I made a pair of UIAlertView and UIActionSheet subclasses that do exactly that. Grab them here:
https://github.com/rydermackay/RMActionSheet
Use them like this:
RMAlertView *alertView = [RMAlertView alertViewWithTitle:#"Alert!" message:nil];
[alertView addButtonWithTitle:#"OK"
action:^{
NSLog(#"OK");
}];
[alertView addCancelButtonWithTitle:#"Cancel"
action:nil];
[alertView show];
EDIT:
From your comments it sounds like you're not familiar with blocks. Read this now. Seriously.
http://developer.apple.com/library/ios/#documentation/cocoa/Conceptual/Blocks/Articles/00_Introduction.html
This is a good one too:

i have a project with many vie controller, in one of these i create and show a view alert. it's possible show alert in every view exclude one?
I need this because if you are in the alarm view controller you don't need to see the alert when alarm ring
i try this but not works!
// ALERT NOTIFICATION
if (!self.timerViewController) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Piccole Ricette" message:#"READY" delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alertView show];
[alertView release];
}
In iOS you can test whether a ViewController 's view is visible by testing the view's window property. If the view is not visible the window property will be nil. So perhaps you can do something like this:
if (!self.timerViewController.view.window) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Piccole Ricette" message:#"READY" delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alertView show];
[alertView release];
}
i have an IBAction which does some processing and within will have a few UIAlertViews (to show alerts). However it seems that the FIRST alert in the paragraph is being called TWICE (once immediately after i clicked and another time after all the other alerts has occured). Additionally, the first time the alert appears, the alert automatically closes even though i have an OK button and the user has not clicked on it. The 2nd time the alert appears, it will require the user to click on OK.
I tried moving the paragraph out from IBAction into its own function but still the problem occurs.
all the alerts in my IBAction/function are the same:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"blah" message:#"blah" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert show];
[alert release];
but the other alerts function normally.
the code looks like this ("blah" is the one being called twice):
-(void)function {
if (......) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"blah" message:#"blah" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert show];
[alert release];
for (int i=0; i<2; i++) {
if (.....) {
//do stuff
} else {
UIAlertView *alert2 = [[UIAlertView alloc] initWithTitle:#"blah2" message:#"blah2" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert2 show];
[alert2 release];
}
}
} else {
UIAlertView *alert3 = [[UIAlertView alloc] initWithTitle:#"blah3" message:#"blah3" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert3 show];
[alert3 release];
}
}
please help!
First of all, we need more code to diagnose your problem. What you provide is not sufficient.
Second, I once encountered a similar problem: when a compose an email action is triggered by the user who didn't set up her email account on that device, I asked my app to show an UIAlertView. However, when I tested my code on a real device with such a scenario, two consecutive UIAlertViews showed, one after another, both of which are about the email account not set up issue.
I finally figured out that the iOS system will automatically show an UIAlertView when the email account is not set up while a user tries to compose an email, which is why two UIAlertViews showed up when I only expected one.
Hope that helps.
